ALFRED GRIEB, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO THE SINGER MANUFACTURING COMPANY, A CORPORATION OF NEW JERSEY.

OVERSEAMING SEWING-MACHINE.

zen of the United States, residing at Elizabeth, in the county of'Union and State of 'New Jersey, have invented certain new and useful Improvements in Overseaming Sewing-Machines, of which the following is a` specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in that class of overseaming sewing machines provided with stitch-forming mechtwo looping implements coperating'therewith, one of which takes the thread-loops from the needle below the work and the other presents loops of thread for passage of the needle above the work.

- The invention has for its object to provide a simple, compact and effective machine of this character capable of operating upon fabrics of all kinds under all ordinary conditions. l

In the preferred embodiment of the lpresent improvement, all of the moving parts are driven by means of cranks and eccentrics upon'the rotary main shaft. The needle-bar carrying the usual eye-pointed needle is mounted in an inclined position upon a bracket-arm extending transversely of the bed-plate and is reciprocated vin such inclined path by a link connection between the same and one end of a rock-lever mounted upon a fixed fulcrum intermediate its ends and having the opposite end connected with one end of an eccentric-rod whose other end embraces an eccentric upon the main shaft. The two thread-carriers, either or both of which may bc constructed and arranged tov carry a lower or locking thread, vibrate upon fixed fulcra in parallel planes transversely of the direction of feed and adjacent the needle path, and are connected to receive synchronous movements by means of an intermediate link. The stock of one of the threadcarrying implements is provided with a lateral crank-arm having a ball-connection with the lower end of a pitman whose. upper end embraces a crank of suitable form upon the main shaft from .which the threadcarriers derive their vibrating movements. its represented in the accompanying drawloops from the needle is itself threaded and Specification of Letters Patent.

delivers its own thread t'o the open-jawed implement or spreader which seizes and spreads it for passage of the needle 'vi-n the succeeding descent of the latter. In some cases it` is contemplated to replace the spreader with a second eyed looper carrying a lower thread whose loop is passed through that of the primary looper and presented 4 for passage of the needle, and it is further proposed 1n certain cases to substitute for the primary thread-carrier an openjawed spreading implement adapted t0 receive thread-loops from the needle and deliver them forpassage of the'secondary looper whose thread is thereafter presented for passage of the needle.y As the production of twoor three-thread overseams has been heretofore eected as described, the adaptability of the present improvement to the described methods of forming the overseam is set forth herein merely to indicate the range of utility of the 'present improvement.

The machinemay be providedA with any usual or suitable feeding mechanism` and with trimming mechanism adjustable transversely of the direction of feed; and it is represented herein with means for guiding a cord along the lower edge of the material to be bound thereto by the overseam.

The invention will be understood by reference to the annexed drawings in which- Figure 1 is a lfront elevation of the machine with the work-plate and lateral coverplates removed to expose the operative parts more clearly; and Fig. 2 is a front end elevation of the 'machine Fig. 3 is a sectional elevation representing the stitch forming and trimming mechanism upon a section line rearward of the bracket-arm. Figs. 4 and 5 are respectively a detail elevation and plan representing the several .members of the stitch-forming mechanism in the positions in which the ,needle is about to descend through the looper-thread distended therefor by the spreader; and Figs. 6 and 7 are respectively a detail elevation and plan representing the stitch-forming mechanism in the posit-ions of its component members as the'spreader is aboutv to engage the looper-thread to carry it under'the needle. Figs. 8, 9 and 10 are respectively, a detached plan view, a front elevation and a partial sectional side elevation of the trimming-shield and the cordguide carried thereby.

vmounted intermediate its ends upon the fulcrum stud 9 carried .by the bracket-arm 3 and having the extremity of its shorter arm connected by a pin/10 .with the upper end of the eccentric-rod 11 whose opposite end embraces the needle-actuating eccentric 12 upon the main shaft 2.

The eyed thread-carrier or threaded looper 13 lis represented-herein of U-shape with the member parallel with the blade adjustably secured by means of a set-screw 14 within a thread-engagin transverse lsocket of the stock or carrier 15 journalcd upon the'iixed fulcrum stud 16 secured to the main frame; 'and the openjawed-thread-carrier Vor spreader 17 is provided with a shank having a lateral foot 18 adjustably secured by means of a screw' 19 upon a'transverse seat formed 'at the upper extremity of the arm 20 of the stock or carrier which is similarly journaled upon the fixed. fulcrum pin 21 secured upon the main frame.

As will be observed, each of the threadcarrying members may be regarded as composed of two parts, comprisingT a thread-engaging implementand vits pivotally mounted carrier. As herein shown and described the eyed thread-carrier thus comprises lthe rier 15, `and the so ca lled open jawed thread-carrier comprises the thread-engaging implement 17 and its carrier 20. For the purposes of the present improvement, broadly considered, it is not material whether these thread-'carriers be each formed of two separate parts, as represented, or whether they be formed each as a single member mounted upon its respective fulcrum, and therefore in certain of the appended claims the carrier for the threadengaging implement is not recited as an essentialfelement. The carrier 2O is provided with a lateral crank-arm 22 the end of which is pivotally connected with the shank of the looper-carrier 15 by means of a short link 23 the crank-arm 22 and link 23 together forming a toggle connection between the loopercarrier and the fulcrum-pin 21. The tubular hub 24 of the spreader-carrier is provided with a radial arm 25 having a ball 26 and guide-pin 27 the ball being embraced by a split spherical socket provided in the lower end of a pitman 28 whoseu'pper end is 0 implement13 and its car` -similarly provided with a spherical socket embracing a crank 29 upon the forward extremity of the main shaft 2, a forked guide i I lug 30 carried bythe pitman 28 embracing the pin 27 for 'retaining the pitman in the required relation with the members which it connects.

A lower-thread lpull-off eye-31 is adjustably secured ,upon the upper side of the crank-arm 22 by means of ascrew 32 passing 'throuji a slotin the fastening foot of the pull-o eye.

The feeding mechanism comprises a feeddog 33 mountedvupon the feed-bar 34 provided with the usual link 35 embracing a feed eccentric upon the main shaft and having its rear end pivotally connected with an upright arm-36 carried by the feed-actuating rock-shaft 37 having a lateral arm 38 connected with-the upper end of a link 39 vwhose lower end is adjustably secured by means of a bolt 40 with the slotted-segmental arm 41 of a rocker pivotally mounted upon a fulcrum pin 42 and having a sec: ond arm 43 'whose extremity is pivotally connected withone end of an eccentric rod 44 having at its opposite end a strap embrac- 'ing the feed-actuating eccentric 45. The

The trimmer-actuating mechanism com,

prises a vibrating bar 48 carrying the knife blade at one end and pivoted at the opposite end upon a fixed fulcrum-pin 49 pivotally connected intermediateits ends by a bolt 50 with the upper end of an eccentricrod 51'whose lower end is provided with a strap 52 embracing the trimmer-actuating eccentric upon the main shaft. The forward end of the trimmer-bar 48 is forked and provided with bearings to receive a tubular knife-carrying shaft 53 having at one end a split head 54 provided with a suitable channel in which the upper knife-'blade 46 is clamped by means of the *fastening screw 55 passing through the hollow shaft 53 and pressing' upon the knife blade 46. The knifeshaft 53 is provided intermediate its bearingswith a collar 56 having lateral projections 57 adapted to embrace the guidebar 58 carried bythe trimmer-bar 48, such collar being adjustably secured uponl the knife shaft by means of a set-screw 59, and a spring 6().is interposed between the collar 56 and one of the knife shaft bearings whereby the upper knife 46 is pressed normally in contact with thev lower knife 4.7. rlhelower knife-blade' is shown fitted to an inclined channel inA a carrier-block 61 and clam edi therein by engagement therewith of' the laterally notched clamping-plug 62 passing throught said block and .terminating ina threaded shank towhichA is applied the milled nut 63 by which thesame is drawn into= operatiye engagement with the blade- 47 entering its notch. The carrier-block 61 is mounted in suitable guidewaysand is provided with lugs 64 having adjustable stopscrews 65 whose points are adapted to bear alternately upon a laterally projecting portion of the main frame to limit the movement of such block and the knife carried thereby'transversely of the direction of feed,

whichA iseffected by means of an adjusting screw 66 tapped into the machine frame andprovided' with a swivel connection with the block G1.- As will be readily understood, the shifting of the working position of the stationary knife 47 produces a corresponding lateral movement of the knife-blade 46 which follows the same under the yielding` action of its spring 60. The carrier-block is provided with ane'edle-guiding blade 67 haNing a chisel-shaped upper edge to insure against the deflection of the needle into the looper' path andi consequent breakage of the needle. y

In practice, the working parts of the machine are inclosed in front by means of suitable cover-plates, one of which is partially represented at 1a in Fig. 3, and the trimmings a-re deflected downwardly from the trimmer-blades by means of an inclined i ,the'trimmer by contact with the upper blade shield-platev 68 having afoot 69 secured to the work-plate 70' by means of shouldered fastening-screws 71 passing through longitudinal slots 7 2 therein. By this means, the operative end portionv of the shield-plate 68 may be shiftedl to follow the adjustments of of the same, anda clamp-screw 75 passing through a slot 76 in the foot is provided for setting the same in the desired position of adjustment.

Tothe upper face of the operative end of the shield-plate G8 is fastened by means of screws 77 the shank 78 of a cord-guiding member 79 which is provided with a longitudinal cord-channel 80. The delivery end of the cord-guide is provided' with a transverse notch S1- so disposed as toldeliver the cord' adjacent to and slightly below the lchainnig-finger SQ of the throat-plate 83, as

indicated in dotted lines in Figs. 8 and 10; and the shank 7 8 of the cord-guide is providedv in its rearward portion with a notch 84' through which the cord is adapted to be led intermediate the tubular portion of the cord-guiding member 79 and the adjacent edge of the shield-plate 68.

The machine is provided with. a wellknown form of presser-bar 85 mounted at one end upon a iXed fulcrum pin 861and provided at the other end with the presser-foot S7 pressed normally upon the throat-plate 83 by means of a spring 88 interposed between 7o the. presser-bar and the head of-the bracketarm 3, and adapted to-be lifted inopposition to said spring by means of a lifting-lever 89 fulcrumed upon the bracket-arm and pr -f vided with a cam-shaped lower-.end adapted 75 to engage a lateral stud 90 upon the presserbar.

ln the use of the machine, the needle thread is led from the source4 of supply to the tensionl 91, thence through the thread-eye 92 o formed in the collar Gand lixed guide-eye 93 downwardly along the needle-bar to the eye of the needle. The looper thread is ledthrough an aperture 9a in the machine frameA 4 to the lower-thread tension 95 and thence 85' In the formation of the ove1'seani,-the-90.l

needle descends through'the throat-plate and in rising presents a thread-loop for' passage of the looper 13 as represented in Fig. 1. rl`he A threaded looper thereupon passes through the needle-thread loop and rises to a position in which its beak is slightly above the throatplate, at which the laterally offset point 17a of the spreader is presented tothe limb ofthe 'looper loop eXtendinp.between its eye and the throat-plate, as represented in Figs. Gand 7. .ln the continued operation of the machine, the spreader advances rapidly to seize the looper-thread loop which slides backwardly upon the laterally offset portion of the spreader against the loop-detaining shoulder 17b as it is carried slightly beyond the needle path, the looper 13 continuing its advance movement a slight distance and then receiving a dwell by reason of the straightening of the toggle-22, 23, as represented in Figs. land 5, in which position of the two lower thread carriers the needle is in the act of making a subsequentI descent to pass its thread through that of `the under thread. In the return of the stitch-forming members to the positions represented in Fig. 1, the looper-thread take-up eye 31 moves rapidly with the retraction of the spreader 17, thereby taking up the slack thread drawn fromI the looper 13 forpresentation to the needle and thus acting toL control such thread throughout the remainder of the cycle of operation of the parts until the stitch is finally setby the completion of the descent of the needle-bar and the tightening of the vneedle thread by means of the take-upl memformed wit-ha lateral recess 13a upon the side adjacent the spreader 17 which affords a clearance space entered by the laterally offset point 17a of the spreader so as 'to insure the seizure of the looper loops; while the lat-v erally inclined slideway afforded by the ofi'- set portion of the spreader serves 'to deiiect the loop held by such member so `,as to insure the proper distention of the looperloop for passage of the needle.
